Inaugurated in 1970 for the Grande Arche La Défense RER station, Boréale is a large bas-relief in stainless steel. The work measures 3 meters in height (in line with the dimensions originally envisaged for the wall on which it is located) and 26 meters in length.

The horizontal lines evoke a dynamic that responds to the vanishing lines of the architectural environment. Two circular elements are visible in the center and slightly to the right.

The work is located at the end of the train on the platform between tracks 1 and A, in the direction of Paris. It occupies the entire back wall. The other ends of the platforms are also occupied by two other works of art: Bas-relief en cuivre occupies the wall of the platform between tracks 2 and B, at the head of the train in the direction of Banlieue; Traits d'union (https://parisladefense.com/en/discover/artwork/traits-dunion) is located at the exact opposite end, at the head of the train in the direction of Paris, and covers the walls of both platforms.

Maxime Adam-Tessier studied with Despiau and then Laurens. This artist, born in Rouen in 1920 and died in 2000, exploded both in France and abroad, distinguishing himself through his almost "cubist" forms, with dense, full volumes. His sculptures have left their mark on many familiar landscapes, including the RER station at La Défense and the church of Notre-Dame-des-Pauvres in Issy-les-Moulineaux. He has taught at London's Royal College of Art.
